there is a way i think but what i do is:
'alt -print screen' this will capture what ever is in the active window at the time and store it in the clip board, then just paste into your prefered program, (photoshop, paintshop pro, painter even MS word'
All you have to do then is cut off the bits you dont wantfrom , fiddle with it change to jpeg and post.

If you do a search in the screenshots forum theres loads of help on this kind of stuff.
hope this helps
